The water level in a test pool changes due to the weather conditions: when the temperature increases some water evaporates, when it’s raining the water level increases. This level can be described by the normal distribution with the mean 20 ft and the standard error 1.8 ft. Find an interval that contains the middle 95% of area in this distribution.

57.09 minus 7.0435 equals

step-by-step explanation:

just subtrach them both and u get the answer of 50.0465

so the possibilities of the measurement of the side of the triangle are either it is longest side or not the longest side

when it is the longest side

s < 25 + 35s < 60

if it is not the longest side

35 < 25 + s10 < sso 10 < s < 60so the perimeter70 < p < 130

well kind of. you get friend requests. and you can accept them or not so yes.
